To construct a perpendicular bisector  you set the compass to a span which is greater than half the length of the given line.  Then setting the point at one end of the line construct an arc  passing through the line . Then repeat this process from the other side of the line keeping the compass at the same setting.

Now draw the perpendicular  bisector through the 2 intersections of the arcs. That's  it.

A road sign has the shape of an equilateral triangle with a side length of 48 inches. What is the height of the sign? The road s
Ivenika [448]

The height of the equilateral triangle is 41. 6 inches. Option C

<h3>How to determine the height</h3>

The formula for finding the height of an equilateral triangle is given as;

h = (a√3)/2

we have a = 48 inches

Let's substitute the value

Height, h = \frac{48\sqrt{3} }{2}

Height = \frac{48 * 1. 732}{2}

Height = \frac{83. 14}{2}

Height = 41. 6 Inches

Thus, the height of the equilateral triangle is 41. 6 inches. Option C

Francis went to the sporting goods store and spent $75.15 on 6 items.
MArishka [77]

Answer:

$6.03

Step-by-step explanation:

The question is asking us how much each pair of socks cost. With the information we are given, we know that there are 5 pairs and that they all cost the same amount. If the total were just the 5 socks, we could easily divide the total by 5 to get the price of each pair but that's not the case. The soccer ball is included in the final cost. To overcome this, we just have to subtract the soccer ball's cost ($45) from the total.

So we subtract $45 from $75.15, giving us $30.15, the total amount of all the socks. However we need to find out how much each pair costs and there are 5 of them, so we divide 30.15 by 5. This gives us the answer, $6.03.

Each pair of socks cost $6.03.

Simpler Explanation:

  • $75.15 - $45 = $30.15
  • $30.15 / 5 = $6.03

The answer is $6.03
